Thanks PoolDoc.

I was thinking about building a little "doghouse" style roof over the pump / motor to mitigate that possibility. I have been wondering how the motor came to have so much corrosion in just 5 years of service and can only imagine that some combination of premature shaft-seal failure or leakage and possibly heavy rain / flooding of the motor vents contributed. I will keep an eye out so I (hopefully) don't have to go through this again in another 5 years!
